I'll tell ya what... Pioneer is great for the low cost of it.
I've never had any problems with Pioneer stuff (btw, my current setup is a Pioneer 7600MP with 4 Pioneer 6x8s... I have these on the HUs high pass. Sound good combined with the sub).
Only Pioneer thing I've had break was my 2001 series CD only player (2nd from the lowest end, had a detachable face). My negative to the car chassis came disconnected with my Walmart-special terminal... since the one to my MTX amp was still connected, guess what happend when I tried to start the car?! Internal amp on the HU fried... I was lucky that's all that happened. Sub still worked perfect.
So what happened was my negative was going from the battery to the amp, thru it to the rca cables, to the HU, thru it to the fuse block or wherever it gets it's neg from! Was real scary trying to start it with "POP POP POP..." going thru the speakers!
